Direct replacement for the STI-6535 and STI-6545
This indoor/outdoor unique polycarbonate cover helps stop false fire alarms without restricting legitimate operation of pull stations. It protects devices such as dual action pull stations, keypads for entry systems, intercom stations, emergency buttons, electrical light switches or duplex plugs, etc. The strong, durable construction takes the toughest knocks while it guards against accidental or intentional physical damage.
This Universal Stopper is a clear, surface mount cover with a red message hood, fire label and red conduit spacer. Other mounting options include a flush mount cover or a waterproof Type 4X enclosed back box (Type rating pending). The cover is also available with a horn housing or message hood. The Universal Stopper is designed to comply with ADA and is less than 4 inches in depth. Universal Stopper has the same footprint as the Mini Stopper® , but has a larger interior and can accommodate most dual action pull stations.
